FRANZ SOHNELL, OF GUTENSTEIN,AUSTRIA-HUNGARY.

WOOD SUBSTITUTE.

Specification of LetteraPatent.

Patented Oct. 6, 1908.

Application filed May 2, 1907. Serial No. 371,513.

To all whom it may concern:

Be it known that I, FRANZ SoHNELL, a subject of the Emperor of Austria-Hungary, residing at Guten'stein, in Lower Austria, have invented certain new and useful Improvements in Wood Substitutes; and I do ereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a new and useful composition of matter and has for its object to provide a substitute for wood'having a lower specific. ravity than and possessing all the technica properties of wood.

My composition consists of the following ingredients, combined in substantially the proportions stated, viz:

Cereal'flour 40 per cent. Wood dust 59 per cent. Fiber lpercent.

A dough is formed of the flour of cereals by the addition of water; in this dough the Wood dust and fiber are mixed in a cold state and the mass molded and hardened. The binding power of the gluten contained in the flour of cereals imparts to the composition a suflicient degree of coherence. After the molding and hardening of the composi-.

either by admixing solutions of coloring matter to the composition or by impregnating or coating the finished articles with such solutions.

My composition is principally intended for the manufacture of small bobbins for thread, silk and the like. The advantages of the bobbins made of this composition as compared with the usual Wood bobbins consists in that the former are much lighter, which involves an important economy in the eX-' portation of thread, silk and the like as the customs duty is calculated by the gross weight.

I claim:

1. A process for the manufacture of wood substitute for the manufacture of turnery ware, consisting in making a thick magma by mixing flour from cereals with water and adding to this magma a large quantity of wood dust and a very small quantity of a fibrous material, the said process yielding a composition of a very low specific gravity.

2. A composition suitable for use as a substitute for wood comprising flour from cereals, wood dust and a small quantity of fibrous material.

,3. A composition suitable for use as a substitute for wood and composed of 40% of flour from cereals, 59% of wood dust and 1% of fibrous material.

4.- A composition suitable for use as a wood substitute, comprising flour of cereals, wood dust, fibrous material and chrome glue.

In testimony that I claim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses.
